Abstract
This toner polyester resin contains 5-30 mass % of a constitutional unit derived from isosorbide, and has a storage elastic modulus (G') at 180° C. of 400-1,000 Pa. This method for producing the toner polyester resin involves polycondensing a mixture containing 5-30 mass % of isosorbide and a polycarboxylic acid at 230° C. or lower, and completing a polycondensation reaction at a softening temperature in the range of 135-150° C.
